So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get…

Alternative energy sources are a big deal these days. One such source is the wind. Find out how a wind turbine can use the power of the wind to generate energy in this science fair engineering project. You'll design various blades to find out which produces the most energy, and put the wind to work for you!

When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project.

It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick—it can make electricity! Electricity can be generated through the flow or through the fall of water. A big, fast-flowing river, for instance, contains a lot of moving energy that provides enough pressure to turn the blades of a turbine and run an electric generator. This same pressure can also be created though…

The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights.

Time Required

Average (6-10 days)

Prerequisites

You should have the patience and dexterity to coil several layers of wire neatly (or find someone who can help you).
You will also need to hook up a basic circuit. Understanding electric circuits is not a prerequisite for this science project, though it will enable a deeper understanding of the electric generator.

Material Availability

A kit containing all the specialty items needed for this project is available from the [# Link Name="Elec_p051.6" Value="HtmlAnchor" #].

Cost

Low ($20 - $50)

Safety

Neodymium magnets are very strong. Follow the safety guidelines in the Procedure for working with these magnets.

The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity.
You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity.

What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic rifle, called a Gauss rifle, of course! Now, this rifle is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the rifle and the ball bearing's initial velocity. This science project makes for…

Time Required

Average (6-10 days)

Prerequisites

None

Material Availability

Specialty items including neodymium magnets and steel ball bearings are needed for this project. See the Materials and Equipment list for details.

Cost

Low ($20 - $50)

Safety

A Gauss rifle can produce high velocity projectiles. Do not aim the gun at anyone or anything; do not put your hand in front of the projectile. Operate the Gauss rifle safely. Be sure to read the important safety notes at the beginning of the Experimental Procedure before you begin. Scissors or other metal objects may be attracted to the magnets; use caution when using metal objects near the magnets.

Did you know that you can actually make objects come together by blowing air between them? Find out how wind changes air pressure to bring to objects together in this easy and fun science fair project!

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will…

You might know that we are able to get free energy from the Sun, the wind, and water, but did you know we can get free energy from Earth itself? The temperature inside of Earth can reach 9,000°F—that kind of heat can be used to make a lot of energy here on the surface! This source of energy is called geothermal energy and it is all about taking advantage of the heat within Earth. So try this science fair project out and find out how to use the heat that lies beneath your feet!
